Here are a few other data points. There is no consensus but either returning 0 or erroring out seem reasonable. MS Excel's COMBIN: If number < 0, number_chosen < 0, or number < number_chosen, COMBIN returns the #NUM! error value. Scipy.misc.comb: If k > N, N < 0, or k < 0, then a 0 is returned. Matlib.nchoose: Error: K must an integer between 0 and N. Maple.numbcomb: Unclear from the docs what this does Wolfram alpha: Returns 0 https://www.wolframalpha.com/input/?i=10+choose+12 ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35431> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
